WATER-TANK HEATER.

SPECIFCATION forming part of Letters Pate-nt No. 773,699, dated November 1,1904. Application led January 1'7, 1903. Serial No. 139,372. (No model.)

T0 (all whom it Worry concern:

Be it known that I, ARTHUR S. ALLENDORPH, a citizen of the United States of America, residing in Alma, in the county of l/Vabaunsee and State of Kansas, have invented a new and useful Improvement in Tater-Tank Heaters, of which the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.

My invention relates to improvements in water-tank heaters.

My invention relates particularly to the class of water-tanks used for watering live stock.

The object of my invention is to provide for the kind of water-tank described an efficient heater which when in operation will prevent the freezing of the water in the tank or which will readily thaw the ice if the water is already frozen.

My invention provides a construction in which the combustion-chamber of the heater is adapted to be inserted in thel water in the tank, a water-conductor being disposed adjacent to and adapted to receive heat from the fire in the combustion-chamber, the said waterconductor being provided with two water-passages, disposed one higher than the other, both of said passages being submerged when the combustion-chamber is properly disposed in the water in the tank. My invention provides, further, a tube connected with the upper of said openings, by which the water heated in the conductor may be carried to any desirable point in the tank. This tube may be of aresilient nature, if desired, thus enabling the operator to heat different portions of the water in the tank consecutively.

Other novel features are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate my invention, Figure 1 is a central vertical sectional view of a water-tank provided with a heater constructed in accordance with the principles of my invention. 1n this view the dotted line a indicates the normal surface of the water. Fig. 2 is a plan view of what is shown in Fig. 1, a portion of the distributing-tube and the tank being broken away. Fig. 3 is a horizontal sectional view taken on the dotted line c lof Fig. 1. Fig. 4

is a bottom View of the upper member or top of the body of the heater.

Similar characters of reference indicate similar parts.

1 indicates the ordinary tank used for watering live stock, provided with a bottom, sides, and an open top and adapted to contain a body of water.

ln the form of my invention shown in the figures the heater comprises a vertical tubular combustion-chamber 2, the lower end of which is secured by a water-tight connection with the horizontal base or lower member 3, provided on its under side with suitable legs 4, adapted to rest upon the bottom of the tank 1. Near the lower end of the chamber 2 is provided a transverse grate 5, upon which the fuel rests. Upon the upper end of the chamber 2 is secured the upper member' or top 6, which is provided with a fuel-feed opening 7, provided with a door 8, hinged to the top. A smoke-vent 9 is also provided in the top and also an opening 10 to admit air into a vertical air-inlet 11, provided at one side on the inner side of the combustion-chamber 2 and having its lower end extending below the grate 5. Encircling and preferably concentric with the combustion-chamber 2 is a water-conductor tubular casing 12, the lower end of which is preferably secured to the lower member or base 3 and the upper end of which is preferably secured to the upper member 6. Below the normal surface of the water and below the top of the combustion-chamber 2 the casing 12 is provided with one or more water-passages 16. Connected at one end with the tube 14, fitted in one of said water-passages, is a tube 15, preferably resilient, the outer end of which is adapted to be disposed where desired in the tank 1 below the water-level. The casing 12 is provided also in a plane lower than the passages 16 with one or more water-passages 13. through which the water enters the annular space between the casing 12 and the side wall of the combustion-chamber 2. To retain the heater in its proper position in the tank, I provide two vertical rods 17, the upper ends of which are provided with heads and which extend through openings provided in the upper member. The lower ends of the said rods IOO are screw-threaded and are inserted in the wooden bottom of the tank 1.

In operating my invention, the parts having been assembled as described, a tire is started in the combustionechamber 2 upon the grate 5, the fuel being inserted in the chamber through the feed-opening. Air to support combustion enters the chamber 2 through the opening l0 and the air-inlet ll, while the products oi' combustion pass out through the opening or vent 9. As the combustion-chain ber becomes heated the water in the annular space between the said chamber and the casing 12 becomes heated and rises and passes out into the tank through the openings or water-passages 16. A portion of the heated water passes through the tube l5, from which it is discharged into the tank in the place where it is desired to water the live stock.

By providing a casing l2 of such a diameter that the annular space between the casing and the side oi' the combustion-chamber '2 is quite narrow great eiiiciency in heating the water may be attained, and a stream of very hot water will be continuously discharged from the end of the tube 15. Thus in very cold weather a pool of water maybe secured by operating my invention, when with a heater not provided with the water heating conductor the effects of the heat are so dissipated throughout the tank that an open pool oi' water cannot be obtained in the tank during eX- tremely cold weather.

My invention may be subjected to various modifications without departing from its spirit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination with a water-tank, ot' a base supported upon the upper side ofthe bottom of said tank, an inner and an outer casing mounted on said base, a top member secured to the upper ends of both casings and provided with an air-inlet, a fuel-inlet and a smoke-outlet the outer casing being provided with holes for the passage of water, and one or more bolts connecting the top member with the tank and securing the top, inner and outer casings and base together.

2. The combination with a water-tank, oi' a base supported upon the upper side ot' the bottom of the tank, an outer casing mounted on said base and provided with holes `for the passage ot' water, an inner casing mounted on said base and encircled by the outer casing and having an air-inlet leading from the upper to the lower end of the inner easing, a grate in the inner casing above the lower end of the air-inlet, a top member mounted on the upper ends of both casings and having a fuel-inlet, a smoke-outlet, and an opening registering with the upper end of the air-inlet, a closure forthe fuel-inlet, and one or more bolts connected to the top member and the tankebottom for holding the top member, the base and the casings together.

In testimony whereof I have signed my name to this speciiication in presence of two sub* scribing witnesses.

ARTHUR S. ALLENDORPH.
